Idaho Mortgage Refinance Calculator

By SoFi Editors | Updated November 20, 2025

Refinancing your mortgage can be a powerful move to manage your finances effectively. However, it’s important to fully understand both the potential benefits and possible costs involved before making any decisions about your home loan. A mortgage refi calculator can be a great resource during this process by providing estimates for your monthly payments, the total interest you might pay over the life of the loan, and your break-even point — the key to determining whether a refinance will save you money.

Key Points

•  An Idaho mortgage refinance calculator can help homeowners decide if refinancing is beneficial.

•  The refinance calculator helps estimate monthly payments, total interest costs, and the break-even point, all key elements to making an informed refinancing decision.

•  Even a small reduction in your interest rate can lead to substantial savings over the life of the loan, making refinancing a potentially advantageous move.

•  Extending the term of your loan can lower monthly payments but increase total interest paid. Shortening the term can do the opposite, so consider your financial goals carefully.

•  Factor in refinancing costs, like origination, appraisal, and attorney fees, which can range from 2% to 5% of the loan amount.

•  Remaining loan balance: The remaining loan balance represents the principal amount you still owe on your home loan.

•  Current/New interest rate: Interest is the percentage of the total loan amount that the lender charges the borrower for the privilege of borrowing money. The difference between your current interest rate and a potential new rate, even by a small amount, can significantly impact both your monthly payments and your overall savings over the duration of the loan.

•  Remaining/New loan term: The loan term represents the duration over which you will be expected to repay your mortgage after completing the refinancing process. Opting for a shorter term can save you a significant amount of money in interest payments over the life of the loan, but it will also lead to an increase in your monthly payments.

•  Points: Mortgage points, also known as discount points, allow you to prepay a portion of the interest due on a home loan at closing. Each point typically costs 1% of the total loan amount and can reduce your interest rate by 0.25%.

•  Other costs and fees: Refinancing your mortgage comes with various costs and fees, including those for the lender, credit report, home appraisal, and attorney. Mortgage refinancing costs typically range from 2% to 5% of the total loan amount being refinanced.

•  Monthly payment: Your monthly mortgage payment typically covers the principal and interest. A refi mortgage calculator can help you compare your current monthly payment with the estimated payment after refinancing to potentially secure better terms. Keep in mind that lower monthly payments alone don’t indicate whether a refinance will save you money over the long term.

•  Total interest: Total interest represents the cost you will pay to the lender over the life of the loan. Compare the total interest paid before refinance with the projected total interest on a mortgage refinance to determine your potential savings.
